COMBINATION EMERGENCY AND TRANSMISSION BRAKE. MECHANISM.

Specification of Letters Patent.

Patented June 6, 1916.

Application filed may 6, 1915. Serial No. 26,340.

Be it known that I, WILLIAM Frreu, a citizen of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Combination Emergency and Transmission Brake Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked form a part of this specification.

. tomvardtv projecting This invention relates to new and useful improven'ients in combination emergency and transmission brakes for automobiles, especially of the Ford type and comprises a simple and cllicient apparatus of this naturc having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claim.

My invention is illustrated in the panying drawings, in which:

Figure l is a top plan view of thc'apparatus. Fig. 2-is a sectional view on line 2-2 of Fig. l. I

Reference now being had to the details of the drawings by letter, F designates a portion of thc'chassis of an;auton |obile hav'- ing rear wheels (l, and L designates cranks for operating the usual brake mechanism to the wheels. I

ilCCOllb.

ll isan emergency brake operating rock' shaft having a lever ll at one end and a arm l l adapted to be actuated by pedal H" in the usual way, and K, arc e'n'ic rgcm y brake rods, having their forward ends. forked and pivotally connected to the"arms I and their rear ends, pivotally connected to the cranks L and are ot' the usual construction found upon the Ford type of automobile.

V A rock shat't llis mounted upon the chassis and has an arm I) fixed thereto which in turn is pivotally connected-at C to a rod B, wlnch latter has pivotal connection with the brake pedal A. Collars J are fixed to the shaft E and have integral arms which are pivotally connected at T to the rods T, which latter have collars T at their rear ends through which-the emergency brake rods K are movable. Collars N are adjustablyheld by means (if. nuts R upon the rods K. f/i I In operationwhen it is desired to relieve the cmergeneyibra'ke mechanism of the strain coming upon the apparatus'when the brake is applied,- the operator by tilting the foot pedal A may cause the rods T to be drawn forward, whichwill cause the collars T to bear frictionally against the collars N, thus causing a longitudinal pulling force to be applied to the rods K through the mediuntof the collars N and T and also through the pivotal connections between the shafts II and K. If desired, however, the emergency brake mechanism may be oper' ated in the usual way independent of the supplemental mechanism shown and described and which forms subject matter of the present application.

\Vhat I claim to be new is Y A brake-lever mechanism comprising, incombination with the frame of a vehicle an emergency rock shaft jOlll'lltllQ(.l,tl19lGOIland having crank. arms fastened thereto, brake rods having slotted ends engaged by said crank, a rocking equalizing bar, leveractuated mechanism for rocking'the same,

collars upon the -equalizing bar and having the movements of the collars at the ends of said rods.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.
